GENERATING PLAN T.

To all whom z't may conccm:

Be it known that I, LEO I. KELLY, a citizen of the United States, residing at Detroit, county of WVayne, State of Michigan, have inyented :a certain new and useful Improvement in Generating Plant-s, and declare the following :to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which t pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My in'vention relates to a steam generating plant for automobles and objects of my improvements are to cheapen the Construction of the generator, to facilitate assembling and disassemblng and to secure certain advantages in the operation of the same hereinafter indicated.

In the drawings:

Figure l is a plan View of a generator embodying Fig. 2 is an elevation of generator.

F ig. 3 is a detail showing a part of the apparatus shown in Fig. 2.

Fig. t is a sectional detail showing the mode of connecting the parts shown most distinctly in Fig. 3.

F ig. 5 is a sectional View of the arrangement in the delivery passages for steam.

As shown in Fig. l there is a casng a in which is inclosed a steam generating apparatus divided into two parts h and h each of the parts is capable of generating partly in section my nvention. a portion of sad steam for power by itself and both deliver' the steam, through the pipes g g and g 9 repectively, into the casing Ic of a throttle Valve by which the rate of delivery of steam to the motor is controlled through the valves i operated by the stem j.

One part IL of the generating plant communicates by pipes g with the casing 70 upon one side of said casing and the part ?a? communicates with said casing upon the other side by the delivery pipes g g 9 9 are check valves in the pipes 9 9 opening toward the casing la. g g* are check valves in the delivery pipes g g opening toward the casing k.

b is a preheating apparatus to which the feed water passes through the pipe f, and

from which it passes, through the delivery pipe c into the generator section k and through the pipe 0 into the generator section h. The preheating apparatus Z is inclosed in a separate 'casing a? which is re- Specificationof Letters Paten't.

moya'bly Secured in an opening in the side of the casing a. The preheater is made up of a series of tii-bes communicating with a delivery manifold 6 which manifold is connected' by unions 6 6 with 'the pipes c and 0 b* 6 *are check valves in the delivery passage :from the economizer or preheater Z to the gene-rator sections opening toward said sections and of course closin-g in the opposite direction. d (Z are cocks adapted to close the passage between the economizer Z and the generator sections h h e is a pet cockin the passage c on the .generator side of the cock d. y

' By loosening the union 6 the economizer b with its casng a may be removed as a unit and Conveniently replaced by'reversing the operation.

If a tube in one of the generator sections h and 71. becomes broken, or the section wall becomes ruptured in any way, the check valves 9 9 or Z will automatically shut off that section from communication with the other section and by trial of the pet cock e the operator can ascertain which section has become broken and close the cock d communicating with said section.

The constituent parts of the generator an upper and lower manifold 'm m (Fig. 3) and these manifolds are joined together by tu'bes or passages constructed as follows: A pipe m is bent into a series of parallel portions joined by curves or loops and this coil is of a breadth proportioned to the length of the manifolds m m and is united thereto as a unit in the following manner: The loops of the coil of the pipe m intermediate its ends are cut away as shown at m and a corresponding aperture is made in the manifold so that these loops are placed so that the apertures register with the apertures of the manifolds and the walls surrounding the aperture in the loop engages the wall around the apertures of the manifold. These walls are then united by welding or brazing as the case may be.

The ends of the pipe m? are preferably contracted as shown at m and pass into an aperture, the outer walls engaging the inner walls of said aperture as shown in Figs. 3 and 4. This forms a Very cheap Construction and one easy to assemble and cheap to replace.

What I claim is:

1. In a generator, two manifolds, a pipe bent into a plurality of loops with approxiinately arallel portions, said loops being provided with openings at their bent por tions, said nanifoids being provided With openings, the openings in said loops registering With the openings in said manifolds and the Walls surrounding said openings being united for the purpose described.

2. In a generator, two manifolds, a pipe bent into a loop With approximately paraiiel portions in a plane passing through the aXes of said nanifolds, said loop being provided with openings at the bent portions, said nanifoids being provided With openings, the openings in said loop registering With the openings in said manifoids and the walis surroundin said openings being united for the purpose described.

3. A structure for generators consisting in a inanifold, a pipe having curved and approxinately parallel portions in a plane passing through the aXis of said manifold,

copies of this patent may be obtained for five cents each, by adressing the said manifold being provided With apertures through its Walls, said pipe being provided With apertures in the curved portions, the apertures in said pipe and said manifold registering and having their Walls united for the purpose described.

4. A structure for generators eonsisting in a manifold, a pipe having curved and ap proxinateiy parallel portions in a plane passing through the aXis of said manifold, said nanifold being provided With aper tures through its walls, said pipe being provided With apertures in the curved portions, the apertures in said pipe and said manifoid registering and having their walls united, an end of said pipe passing through an aperture in said manifold and being Secured therein.

In testimony Whereof cation.
